I've uploaded a file - jmkac.zip - to my OneDrive at Noel's OneDrivePlease download and save it.Right-click on the downloaded file, and select Extract all…Extract to the default location - which will create a new folder jmkac in the same place.Open this folder - there should be one folder inside it (Packages)

Copy the content of the Packages folder to the folderC:\Windows\Temp\CheckSur\Servicing\Packages

When I do this it says that "there is already a file with the same name in this location", also saying there are 7 other conflicts. What should I do? Copy/Replace, Keep both, or not copy? I've attached a screenshot in case.

OK - that means that the problem is a little different, and lies within the registry rather than the file system.

abandon that for the moment.

I need to have a look at your COMPONENTS registry hive

Please copy the C:\Windows\System32\config\COMPONENTS file (no extension) to your desktop and then compress it - upload the compressed file to your favoured fileshare site (preferably Dropbox or OneDrive) and post a link.

Also I just had a couple of quick questions that doing all this has brought to my attention.

The first one would be whether doing things like SFC and CheckSUR's can help with computer performance in general, and in that case whether it would be recommended that the average computer user use these tools as part of regular maintenance. And the second one (perhaps rooted more in paranoia than just curiosity ) is how these errors and file corruptions could have happened, as in could a virus have caused this or is it just some normal thing that happens to all computers. I'm asking this since you mentioned earlier that I was missing some critical files as well as recently having a virus scare on my other computer.

Other than that really appreciate you doing all this, I can imagine how stressful doing stuff like this can be sometimes

It looks to me as if someone has been using some form of registry cleaner - and because there were errors in the registry, the cleaner, rather than repairing things, has comprehensively trashed them.
I don't think there's a lot I'm going to be able to do with it, apart from recommend a repair install

As to what caused the initial error, the common causes are BSOD during updating, power-out during updating, registry cleaners, malware, etc., etc..

I'm going to ask someone else to have a look and see if he can come up with a better prognosis for you, but it may be a couple of days before he can free the time to get back to you.

Nope never even heard of the other two, CCleaner is the only Registry Cleaner I've ever used. Anyways, I merged all the backups from the CCleaner Backup Files folder, which it reported was successful. The files are still there in the folder. Not sure if that's just normal or whether they were supposed to disappear after merging. Anyways, I then restarted the computer after which everything seemed to be normal. I proceeded to do your previously mentioned instructions of copying the COMPONENTS file and am posting the dropbox link to the new one.

Installation & Setup

Unable to install Windows 7 Home update to Windows StarterI bought Home Premium 32 bit update (at Office Max) to install on my ASUS 1015 PEM Notebook (upgrading Windows Starter).
